The Cardiff scheme for reporting violent cases anonymously have been appraised by World Health Organization. It has been revealed that the scheme has been successful in reducing the crime rates in the region. The schemes suggest that more accurate targeting led to faster and more frequent police intervention.

Professor Jonathan Shepherd, who led the Cardiff Violence Prevention Programme, said, "All this work was built on the shock finding 15 years ago that all violent incidents are not known to the police, mainly because they aren't reported".

It has been revealed that injuries occurred by knifes and shooting are often not registered with police. Under the scheme the hospital authorities inform the police without revealing their names. Violence is a serious offence it is believed that if the health and police authorities work together it can be eradicated.

This scheme in Cardiff was developed over 15 years. It has been told that the success of the scheme is wholly depends upon the partnerships shared between the police, NHS and local council. The success of the scheme suggests that communities can achieve substantial reductions in the public health burden of violence through organized data driven partnerships between health, law enforcement agencies, and local government.
